Just trying to find some good examples for the broadcast of Dutch station VPRO over the years. But will take some time probably.
While looking I stumbled over this one: Sly and the Family Stone - Piknik VPRO 1971FM - 1970-09-10. It is up here on the Den. Looks pretty modern for its age.

Hope you find some. But better not try VPROs. Dl'ed one track from 3 or 4 of their old ones now and all looked modern. And the uploaders all stated that this was from 60s or 70s broadcast.
And, well, the other way round. I was asked on DIME to have a look at some BBC sessions from Sleater-Kinney someone wants to upload there. I don't know the date of these shows but this band exists since around 1995 only. And two of those look exactly like a bad 80s FM. Not lossy and not completely dark above cutoff but one cuts off at 8 Khz, the other at 10 Khz. Did you ever see something new which looked bad like that?

that springsteen doesn't look typical at all! maybe its prefm? or somehow a lot of highs have been generated...

another thing that dawned on me is that cassettes can't record the upper highs so that's probably why I'm having trouble finding older fms with the carrier visible.

Pawel, the first three are pretty decent, look to be similar in quality to an MD (atrac) recording. but the 4th is lower-quality than 128kbps cbr mp3.

I don't understand the bitrates... the one that says '192kbps' is not like an mp3 at 192kbps I guess its something with the different codec?

I'm not sure how we would go about allowing the kind of captures you're posting... so long as its recorded well and the cutoff it above 16kHz it would be similar or slightly better in quality than some of the modern fm 'open air' broadcasts we've allowed here. Right now we have the advantage of allowing stuff taped from the open air and not allowing stuff that isn't. Its a real can of worms to try to suss out which digital sources are okay and which are not. They usually don't look (or presumably sound) as high quality as the first three you've posted above.

After being asked the uploader stated: 'Yes, i used the dehisser-function from magix and something else'.

Sa and Fa look different now clearly. The result of dehissing? Or was it the 'something else'?
Actually I think it sounds worse now than before when listening to it on my computer. 'Though the difference is not big.

I found this broadcast from 1997. Looks good. But carrier is much weaker. Concert was in Hamburg. Station wasn't mentioned, unfortunately. But probably it was aired by one of those North German stations.
